Benefits of technology

[0010]In light of the aforementioned problems associated with the prior devices and systems, it is an object of the present invention to provide a Swing-arm Integrated Exhaust Silencer. The Silencer should be incorporated within the conventional swingarm of a motorcycle. One version should have a removable silencer cartridge that installs within the inner chamber of the motorcycle's swingarm. Another version should simply allow the exhaust stream to be diverted from the conve

Problems solved by technology

There are at least two problems with this prior design: its weight and its lack of performance.

Embodiment Construction

[0018]The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the generic principles of the present invention have been defined herein specifically to provide a Swing-arm Integrated Exhaust Silencer.

[0019]The present invention can best be understood by initial consideration of FIG. 3. FIG. 3 is a partially cutaway perspective view of the motorcycle of FIGS. 1 and 2 having a preferred embodiment of the present invention installed thereon. The invention is a swingarm-integrated exhaust silencer assembly 40. The assembly 40 seeks to divert the exhaust gases from the engine so that instead of entering the exhaust pipe 18 and silencer 16, they travel through an integral silencer element 42 that is actually located within the hollow inner chamber of swing...

Abstract

A Swing-arm Integrated Exhaust Silencer is disclosed. The Silencer is designed to be incorporated within the conventional swingarm of a motorcycle. One version has a removable silencer cartridge that installs within the inner chamber of the motorcycle's swingarm. Another version allows the exhaust stream to be diverted from the conventional silencer and into the inner chamber of the swingarm. In either version, the swingarm has plurality of apertures formed in it to allow for exhaust gas exit. The invention includes an adapter device that splits the exhaust gas exiting the engine and redirects it into the swingarm-integrated silencer. The exhaust adapter device is somewhat flexible to allow for movement between the swingarm, the engine, and the conventional silencer's exhaust pipe.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to motorcycle engine exhaust systems and, more specifically, to a Swing-arm Integrated Exhaust Silencer.[0003]2. Description of Related Art[0004]Motorcycles are available in a variety of shapes, sizes and configured for different environments. The portion of the conventional motorcycle that is the subject of this invention is related to the engine exhaust and sound suppression system. Each type or class of motorcycle has an exhaust and noise suppression system specific to the use pattern of that type or class. For example, a “street” cycle exhaust system design will emphasize aesthetic physical appearance as well as richness of sound. In some of these “custom” street bikes, extensive research is used to arrive at a particular sound quality and engine performance traits. In contrast, designs for off-road motorcycles place almost no value on the aesthetics or sound qualities. The most impo...
